Engine ping is usually caused by bad spark plugs. Typically the spark plugs become worn out and do not detonate the cylinder at the proper time. I would recommend having a tune up performed by a technician. Spark plugs and wires are recommended for replacement at ~30,0000 miles. It is also possible to get better plugs and wires that will last significant longer.
